V1 B Patented June 23, 1931 'UNITED STATES PATENT OFFICE JOHN B. IELYNN,v OF DETROIT, MICHIGAN, ASSIG'NOR TO TERNSTEDT MANUFACTURING COMPANY, OF DETROIT, MICHIGAN, A CORPORATION OF MICHIGAN COACH LOCK Application led January 4, 1929. Serial No. 336,241.l

This invention relates to a coach lock for automotive vehicles and the like.

'It is the object of this invention to present a lock having a longitudinally operated handle sha-nk, the operation of which serves to either lock or unlock the lock.

In the drawings:

Fig. 1 is an elevation of the lock.

Fig. 2 is a section on the line 2 2 of Fig. 1.

Fig. 3 is an elevation partly in section with parts broken away showing the relative position of the various parts in locked condition.

Fig. 4 is a view similar to Fig. 3, showing the relation of the parts when the lock is unlocked.

Fig. 5 is a section along the line 5--5 of Fig. 3.

Fig. 6 is an end view of the longitudinally operable spindle.

Referring more particularly tothe drawings, the lock consists of a front plate 1, a bolt 2 which may be retracted against the action of the bolt spring 3 and of a cover 4. The bolt is adapted to be retracted by the turning of the handle 5 which is mounted upon the spindle 6 and thereby operatively connected with a roll-back 7 which slidably engages the roll-back abutment 8 thereby causing the bolt to be retracted. Mounted upon the coverby any suitable means such as the rivets 9 is the spindle abutment 10. The spindle abutment 10 has a right angled recess as at 11 the purpose of which is explained below.

The spindle consists ot' the part 12 which has a press fit in the bushing 32 and which serves as a guide for the longitudinally slidable part 13 which has a slip t in the bushing 32 and is guided thereby. The part 13 of the spindle has a head 14 adapted to engage the spring 15 which is seated in the hole 16 in the end of the part 12. The hole 16 is bored into the end of the part 12 of the spindle 6. The shank part 13 is recessed as at 17 and the spindle part 12 is recessed as at 18.

These recesses areot a width greater than the Y thickness of the spindle abutment 10. Fixedwithinthe handle 5 is the sleeve 19 and rotatively mountedwithin the sleeve 19 is the cam cylinder 2O having a c-amportion 21. The cam cylinder is circumferentially grooved as at 22. The pin 23 secures the cam cylinder 2O within the sleeve 19 and slidably engages the cam cylinder 2O in the groove 22v whereby the camk cylinder is permitted to Yrotate in the sleeve 19 but not to move longitudinally upon actuation of the key 24. The :Sleeve 19 is held in the handle by the pinv 31.

The operation of the lock is nicely shown -by the figures 3 and 4. As shown in Fig. 3, the cam cylinder 20 has been rotated by .means of the 'key 24 which has caused the cam portion 21 to slidably engagethe head 14 4whichin turn has moved the spindle part 13 longitudinally against the action of the spring 15 which is now contracted. In this 'position the lock is locked because of the lfact that the recess 17 has been moved beyond the spindle abutment 1() thereby causing the lsquare shoulder of the spindle part 13 to abut .in the recess 11 of the spindle abutment 10 as shown in Fig. 5. Hence, the handle 12 can- -not be turned when the recesses are in this position because at this time the square shoulder of the part 13 of the spindle lits within the right angled recess 11 and thereby prevents any rotation ot the lock handle.

As shown'in Fig. 4, the cam cylinder 20 has been rotatedA by means of the key 24. The headV 14 has slid to the low part ofthe cam portion 21 and the expansion of the spring 16 has moved the slidable part 13 of the spinydleso that the recess 17 now coincidesboth with the recess 18 and the spindle abutment 10. Owing to the coincidence of the recess 17 and 18, the spindle presents a circular instead iof a squared shoulder within the right angled recess 11 ol' the spindle abutment 10, hence, in this condition vthe lock handle may be turned. and the boltretracted since the spini dle 6 will not be retarded by the abutment 10 erating with said relatively movable recessed parts tollock and unlock said handle.

A2. In a lock, a handle having a plurality of parts adapted for longitudinal relative movev ment, said parts having recessed portions, and means adapted tolock saidhandle when the recessed portions of said longitudinallyL movable parts are disaligned.

`3. In alock, ahandle spindle 'having a f plurality of relatively longitudinally movable parts, said parts vhaving v recessed portions, means cooperating with said longitudinally movable partsto look said handle when `the recessed vportions are oE-set one from the other.

. 4.v In a lock, a handle spindle having a plurality, of relatively longitudinally movable l rality of parts adapted for relative longitudinal movement, each of said parts having-a recessed portion and a shouldered portion, and an abutment plate Vhaving a recess adapted to cooperate with the shouldered portions to lock the said handle spindle and adapted to cooperate with the recessed portions to un- Y lock the said handle spindle.

In testimony whereof I have aiixed my signature. f

parts, a cylinder within saidhandle adapted f forV rotative movement having a cam head arranged to .slidably engage -a part ofthe shank and a circumferential groove, and4 a pin adapted to slidably engage said groove whereby the cylinder may be rotated to effect relal tive movement between the parts of said handle spindle. i

5.v In a door lock, a handle spindle having a plurality of square shouldered parts, said v partsv having recessed portions Yand adapted Jfor relative longitudinal movement, and

means vadapted to'engage the square shouldered portions of said relatively'movable parts to locksaid handle and adapted to unlock saidhandle when the recessed portions are adjacent to said means.

6. yIn a lock, a handle spindle having aplufrality of'parts'adaptedfor-relative longi- .el

tudinal movement, each of said parts having 1 a recessedportion anda square shouldered portion, and means having a rightvangled recess adapted to cooperate with Vthe square Y shouldered portions to lock said handle spindle .and adapted to cooperate with the recessed portions to unlock said'handle spindle.
